Zy. Teng et Fe. Teng, THE MESOSCOPIC APPROACH AND CONSTITUTIVE-EQUATIONS FOR CHARACTERIZINGMECHANICAL-PROPERTIES OF ALLOYS CONTAINING 2ND PHASES, Materials characterization, 38(4-5), 1997, pp. 229-232
This paper discusses the feasibility of characterizing mechanical prop
erties of materials by using a mesoscopic approach. Based on the mesos
copic system with the dislocation substructure at the core, the equati
ons for flow stress and microhardness of alloys with second phases are
proposed. The flow stress equation is experimentally verified. The pr
oblems are grouped so as to build the universal, quantitative, and con
stitutive equations relating the external properties and internal stru
cture of materials. (C) Elsevier Science Inc., 1997.
